摘要

Production of a biofuel from biomass, comprises decrease of the oxygen content of the biomass to be processed by composting to obtain a compost and biogas, recovery of the formed biogas, production of dihydrogen from the recovered biogas and catalytic hydrocracking/hydrogenolysis of the compost using the dihydrogen to obtain a liquefied product used as biofuel. An independent claim is included for a biofuel obtained by the process in which the hydrogenolysis is done at 350[deg] C, the tetraline/compost ratio is 3, the hydrogen pressure is 10 MPa, the catalyst is palladium on alumina, comprising carbon (89%), hydrogen (10%) and (oxygen), having an intrinsic calorific value of 41 MJ/kg.
